多选题 A network engineer is designing the architecture for a healthcare company's workload that is moving to the AWS Cloud. All data to and from the
On-premises environment must be encrypted in transit. All tra¨c also must be inspected in the cloud before the tra¨c is allowed to leave the
Cloud and travel to the on-premises environment or to the internet.
The company will expose components of the workload to the internet so that patients can reserve appointments. The architecture must secure
These components and protect them against DDoS attacks. The architecture also must provide protection against ¦nancial liability for services
That scale out during a DDoS event.
Which combination of steps should the network engineer take to meet all these requirements for the workload? (Choose three.)

B、 Set up AWS WAF on all network components.
C、 Con¦gure an AWS Lambda function to create Deny rules in security groups to block malicious IP addresses.
D、 Use AWS Direct Connect with MACsec support for connectivity to the cloud.

单选题 A company uses a 4 Gbps AWS Direct Connect dedicated connection with a link aggregation group (LAG) bundle to connect to ¦ve VPCs that are
Deployed in the us-east-1 Region. Each VPC serves a different business unit and uses its own private VIF for connectivity to the on-premises
Environment. Users are reporting slowness when they access resources that are hosted on AWS.
A network engineer ¦nds that there are sudden increases in throughput and that the Direct Connect connection becomes saturated at the same
Time for about an hour each business day. The company wants to know which business unit is causing the sudden increase in throughput. The
Network engineer must ¦nd out this information and implement a solution to resolve the problem.
Which solution will meet these requirements?

The highest throughput during the period in which slowness is observed. Create a new 10 Gbps dedicated connection. Shift tra¨c from the
Existing dedicated connection to the new dedicated connection.
B、 Review the Amazon CloudWatch metrics for VirtualInterfaceBpsEgress and VirtualInterfaceBpsIngress to determine which VIF is sending
The highest throughput during the period in which slowness is observed. Upgrade the bandwidth of the existing dedicated connection to 10
Gbps.
C、 Review the Amazon CloudWatch metrics for ConnectionBpsIngress and ConnectionPpsEgress to determine which VIF is sending the
Highest throughput during the period in which slowness is observed. Upgrade the existing dedicated connection to a 5 Gbps hosted
Connection.
D、 Review the Amazon CloudWatch metrics for ConnectionBpsIngress and ConnectionPpsEgress to determine which VIF is sending the
Highest throughput during the period in which slowness is observed. Create a new 10 Gbps dedicated connection. Shift tra¨c from the
Existing dedicated connection to the new dedicated connection.
多选题 A retail company is running its service on AWS. The company’s architecture includes Application Load Balancers (ALBs) in public subnets. The
ALB target groups are con¦gured to send tra¨c to backend Amazon EC2 instances in private subnets. These backend EC2 instances can call
Externally hosted services over the internet by using a NAT gateway.
